WIRE STRAIGHTENING AND SWAGING liTACHI'NE.

Application filed June 14,1922. Serial No. 568,307.

. To all whom it may concern:

Be it known that we, Am J. GERRARD and PARVIN Vvnlorrr, respectively asubject of the King of Great Britainand a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in. Wire Straightening andSwaging Machines; and we do herebyde- 1o clare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and'use thesame.

This invention relates to a wire straightening and swaging machine andhas for its object to provide a machine which will be more eflicient inaction and less costly to construct than those heretofore proposed.

With these and other objects 1n view the invention consists. in thenovel details of construction and combinations of parts more fullyhereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of thisspecification, in which like numerals designate like parts in all theviews Figure-'1 is a side elevational view of a machine made inaccordance with this invention;

Figure 2 is a plan view of the parts shown in Figure 1;

Figure 7 1s a detail view of the swaged '45 wire showing how the swagedparts are cut in two.

1 indicates any suitable base or support on which is mounted the shaft 2of any suitable motor 3 provided with the power W pulley 4 around whichpasses the belt 5.

fit the springs 21, the upper ends of which Said belt also passes overthe power pulley 6 rigid with the power shaft 7 carrying the pinion 8,meshing with the gear 9, mounted on the short shaft 10, carried by theswing- '16 and 17 as best illustrated in Figure 4,

and above these cams is positioned the swaging bar 18 provided with aplurality of die members 19 as shown. The said swagingbar is recessed ateach end as indicated at 20 and 22, and into said recesses rest in therecesses 22 with which the cap members 23 are provided.

25 represents a stationary swaging bar provided with pivoted supports 26resting in said cap members 23, and also carrying at its lower surfacethe swaging die members 27 as shown. The cams 16 and 1.7 dip into theoil cups 30 carried by the brass bushings, and are thereby kept incondition. The wire 35 comes into the machine from coils not shown,passes over pulleys 36, pivoted as at 37 to the levers 38, pivoted at 39in the brackets 40 and provided with the notched trigger members 41.Goactin with each trigger member 41, is a pivot tri'gso ger 42 rigidwith thecutting member-l3v into which the wire 35 passes into themachine and which is controlled by the spring 44. Should the. wire inits travel become knotted or tangled, its pulley 36 will be elevatedwhich will depress its corresponding notch 41, thus releasing thetrigger 42 which'causes the cutter 43 to sever the same, and thus willthe particular tangled wire not stop the operation of the machine.

After the wire 35 has thus passed the cutter 43 it enters the barrel 45of I the straightening mechanism 46, which is pro vided with the worm47'engaging thegear 48,'Inounted on the shaft 49 operated by thesprocket 50, see Fig. 2, rigid with the shaft 7 over which passes thebelt or sprocket chain 51; Said chain 51 also passes over the sprocket52 rigid with the shaft 49 and thus is the worm 47 and'barrel 45lturned,The 100 continuous and is provided 'with grooved surfaces as bestindicated in Fig. 3, while a plurality of short rolls 56 are mounted onshort stud shafts 57 carried in the individual frames 58. Each of theshort. rolls 56 are provided with grooved surfaces 59 which are adaptedto coact with the grooved surfaces of the rolls 55, and to frictionallyengage the wire' strands between them. Each of said rolls 56 is providedwith a gear 60, as best shown in Fi res 2 and 3, and the roll 55 isprovided with a plurality of similar gears 61 which mesh with said gears60; and thus are the individual short rolls 56 positively turned fromthe continuous longer roll 55. As will be readily understood from Fig. 2of the drawings, there are a plurality of wires being drawn through aplurality of straighteners 46, and

.undera plurality of cutters'43, simultaneously.

- After a wire strand 35 is thus forcibly drawn through its straightener46, it is.

pushed forward by the said rolls 55 and 56 between the cutting andswaging dies 19 and 27, as will be clear from Figures 3 and 4. Theswaging die 27 is held stationary in its supporting ar 25 while theswagin die 19 is raised vertically by the action of t e cams 16 and 17to cut and deform the wire into the shape shown in Fig. 7. That is tosay, in the types of wire tying machines which have been recentlydeveloped, it is very desirable indeed that the tie wires be providedwith the depressions such as 62 providing the holding shoulders 63 ineach end of the -,wire and this machine accomplishes this It is oftenconvenient to change and to re pair the cutting dies 19 and 27 and withthe construction just illustrated, by loosening up a few bolts and nutsthe bar 25 can be readily turned-onits pivots 26 through an angle of 90or 180 which notonly exposes the die member 27, but also the die members19. This movement of the bar 25 will be readily understood from thedetailed view shown in Fig. 6, wherein there is shown a. stationary stopmember 81, ada ted to contact with one side of the pivot swaging bar 25,as well as a pivoted stop member 82 ada ted to contact with the otherside of sai bar 25. The members 81 and 82-are conveniently secured tothe capmember 23, and the member 82 is ca able of swinging around itspivot 83, to re ease the bar 25 and permit it to swing from its fullline osition to its dotted line position shown ,in' igure 6.

During the cutting and swaging o eration it is desirable that themotiono the various wires 35 be stopped andzto this end the swaging plate 18is provided with the extension 65, best shown in Fi 3, on which reststhe set screws 66 with w ich the various individual frames 58 areprovided. It thus results that when the swaging plate -or bar 18 iselevated to deform the wires 35, all of the frames 58 are raised attheir ends carrying the screws 66 and the raising of these ends raiseseach individual short roll 56a very slight distance.

This said distance is suflicient to decrease the friction between theseveral rolls 56 and the several surfaces of the roll 55 so that thevarious wires are stopped in their motion. The said frames 58 arepivoted on s'tuds 96 indicated in Figures 1 and 2, to permit this slightmovement. Said short frames 58 are also provided with adjustable screws97 resting upon the frame work, as best shown in Fig. 1, in order'thatthe desired friction on the wires may be accurately attained.

After the various wires 35 are thus deformed and severed in the mannerdisclosed, their cut ends are carried out of the machine by means of therolls 70 and 71mounted on the shafts 72 and 73, respectively. The shaft72 is driven by the sprocket 75 ri id therewith, over which passes thesproc et chain 76 driven by the sprocket 77 rigid with the power shaft7, as will be clear from Fig. 2. I

As these straightened out and swa ed tie wires are intendedto band boxesan packages of various sizes, it is evident that a single length of wirewould not be suitable for all purposes. Therefore, it is desirable tochange the lengths of the wires cut by this machine. In order to dothis, it is only necessary to change the multiplying gears 9 and 13.These said gears are carried on the lever like means 11 which ispreferably made of two parallel arms as best shown in Fig. 4. These saidarms carry thestuds 80 between which are mounted the gears 9 and 13, sothat it is only necessary to remove the said gears and their pivot 10and to sub stitute gears of the proper size'to feed the desired lengthsof wire through the swaging mechanism before the cutting action takesplace. a

It is obvious that those skilled in the art may vary. the details ofconstruction as well as the arran ement of fparts without departing fromt e spirit 0 the invention, and therefore, it is desired not to belimited .to the above disclosure except as may be required by theclaims.
